Dear Longevity Insider,

Epigenomics is the study of the complete set of epigenetic modifications on the genetic material of a cell, known as the epigenome.

The epigenome consists of a multitude of chemical compounds that can tell the genome what to do. The genome is passed from parents to their children and from cells, when they divide, to their next generation. Much of the epigenome is reset when parents pass their genomes to their children; however, sometimes, can be inherited from generation to generation. Interestingly, lifestyle and environmental factors (such as lifestyle, diet, and disease) can expose a person to pressures that prompt chemical responses which result in changes to the epigenome throughout a person’s life. Epigenomics is a fascinating field as it is vital to better understand the human body and to improve human health. Emerging epigenomic map technology will facilitate better prevention, diagnosis, and treatment of disease.

Microbiomics

Microbiomics is the study of microbial cells – including bacteria, fungi, protozoa, and viruses that collectively constitute the microbiome. The human microbiome is the aggregate of all microbiota in a human body. A large body of research has demonstrated a strong association between the gut microbiome and disease. Microbes ( a microorganism) have been associated with neurological disorders ranging from degenerative diseases (such as Alzheimer’s, Parkinson’s, ALS, and dementia) to mental health disorders (such as depression and anxiety) that are becoming, unfortunately, commonly diagnosed today. Microbiomics is a key component in personalized medicine as novel correlations between the human microbiome and health and disease are routinely emerging, furthering our quest for personalized medicine.

Pharmacogenomics

Pharmacogenomics assesses how individual genes affect drug interactions. It has been found that the same drug may produce variable effects on different individuals based on the differences in their genomic background. Genetic information could thereby assist in assigning drug doses to individuals based on their needs. It could also be very helpful in reducing the adverse effects associated with drugs.

Advantages

Omics testing is a very promising technology with a huge number of potential benefits. Capable of revolutionizing the healthcare and drastically improving health and lifestyle, this technology anticipates the development of personalized medicine.

In addition to its impact on patient care, it will also allow a deeper understanding of the disease pathogenesis, early diagnosis and intervention. Biomarker discovery is another potential advantage of Omics testing that will revolutionize diagnosis allowing us to delve deeper into disease risk factors and causes. Omics testing as a whole would be able to answer the problems arising from the complexity of the disease phenotype. Biomarker discovery is another potential advantage of omics testing providing useful signatures of disease. Pharmacogenomics will be relevant in clinical decisions about prescribing the best medication for you.

Future of Healthcare

Personalized Medicine has become the most modernized trend disrupting the healthcare industry in the most recent years. There has been a paradigm shift from ‘one-size -fits all” towards a precise and personalized approach.

The quest for personalized medicine has resulted in various advancements to achieve targeted care paths with a personalized multi-omics approach. With new technology, the interrelationships between the human genome, the microbiome, the metabolome, the proteome, the epigenome, the transcriptome, and other factors have shown to provide a better picture of our health journey, are just starting to be revealed. Researchers and clinicians have access to a new and thorough view of the molecular manifestation of diseases and with emerging technologies, can translate that into helpful advice that can be used in the prevention of diseases together with improved diagnostics and cure.

In the future, Omics-data will utilize the patient’s individuality including their genetic make-up, lifestyle, and exposome which is defined as the “ totality of exposure individuals experience over their lives and how those exposures affect health. “ in decision making when it comes to disease management.

And as this manifests and unfolds, I'll keep you posted!
